Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a back plate of a rear combination lamp to which a lamp holding device according to an embodiment of the present invention is applied. In FIG.
Numeral 0 is formed in the shape of a square basin that is raised from the peripheral portion of the rectangular bottom plate 11 upward to form a peripheral wall 12, and a connector 20 is provided at one corner of the rectangular bottom plate 11 by cutting the raised peripheral wall 12. On the upper surface of the bottom plate 11, a holding rib 13 for holding the electric wire at a predetermined position and a press-contact rib (wire holding tool) 14 for holding the electric wire so as to be press-contactable are formed to protrude.

The holding rib 13 is formed with one to three wire grooves 13a which are slightly narrower than the wires and have an opening above. Further, two similar wire grooves 14a are formed in the pressing rib 14 in the width direction of the rib. Further, the pressing rib 14 is formed with a terminal groove 14b into which a pressing terminal metal fitting to be described later can be inserted in parallel with the thickness direction of the rib. On the other hand, a pair of socket fixing bosses 15 are formed so as to protrude at a position slightly apart in the width direction of the press contact rib 14 on the substrate 10 to fix a socket described later. As shown in FIGS. 3 and 4, the socket 30 is provided with a lamp 4 at the bottom of a cylindrical portion 31 having a circular opening at the top.
A groove 32 in which a flat plate-shaped portion 41 formed at the lower part of the socket 30 can be inserted is formed, and a pair of terminal holding grooves 33 communicate with the groove 32 from below the socket 30. A terminal 50 is inserted into the terminal holding groove 33, and the terminal 50 is formed with an electrode portion 51 capable of holding the... 41 of the lamp 40 by facing a flat spring facing an upper end portion, The lower end portion is provided with a press-contact portion (press-contact terminal) 52 having a slit-shaped notch 52a having an opening at the bottom at the end of the plate-like portion extending downward. In addition, an electric wire holding hole 52b whose inner diameter is slightly wider is formed in the notch 52a.
A locking portion is formed in the terminal holding groove 33 to prevent the terminal 50 from coming off when the terminal 50 is inserted.

Further, a pair of fixed legs 34, 34 are formed on the lower side of the outer periphery of the socket 30 with the terminal holding groove 33 interposed therebetween, and the lower ends of the fixed legs 34, 34 are mutually outward. The fixing holes 34a, 34a into which the socket fixing boss 15 can be inserted are formed. Next, how to assemble the present embodiment having the above configuration will be described. The connector 20 to which the electric wire W is connected is prepared in advance, and the connector 20 is attached to one corner of the substrate 10.
The attachment of the connector 20 is generally performed by engaging irregularities formed on the substrate 10 and the connector 20, but may be attached using an adhesive or the like. After the connector 20 is attached, the wires W are wired into the wire grooves 14a of the press-contact ribs 14 while being pushed and held in the wire grooves 13a of some holding ribs 13 formed on the substrate 10. In this example, there are two press-contact ribs 14, and two of the three wires W are wired to the respective press-contact ribs 14 on the plus side, but one is connected to the minus side and one of the press-contact ribs 14.
To the other press-contact rib 14 via. Conventionally, when wiring the electric wire W to a plurality of sockets,
Although the middle of the electric wire was peeled off and another electric wire was connected, and a tape was wound thereon to insulate the electric wire, according to the present embodiment, the common electric wire W was sequentially passed through the pressure contact ribs 14. It can be wired simply by holding it in the wire groove 14a. Note that the wiring work of the electric wire W may be performed manually or may be mechanically wired by a wiring device.

On the other hand, regarding the socket 30, the terminal 50 is inserted into the terminal holding groove 33 from the side of the electrode portion 51 in advance and assembled. Then, the terminal 50 is pressed toward the substrate 10 by aligning the plate-shaped press contact portion 52 of the terminal 50 so as to enter the terminal groove 14 b of the press contact rib 14. Then, the wire W held in the wire groove 14a of the press-contact rib 14 is pressed into the press-contact portion 5.
The two slits 52a are pressed against the same slit 52a.
Cuts the sheath of the electric wire W and comes into contact with the core wire. And
When the wire is further pushed in, the core wire abuts against the wire holding hole 52b, and the fixing leg 34 comes into contact with the substrate 10, so that it cannot be pushed any further and is stabilized at that position.

When the press contact portion 52 and the wire groove 14a are aligned, the socket fixing boss 15 on the substrate 10 and the fixing hole 34a formed in the fixing leg 34 of the socket 30 face each other.
When the socket 30 is pushed in, the socket fixing boss 15 is inserted into the fixing hole 34a. In this state, the socket fixing boss 15 is melted from above to prevent the socket fixing boss 15 from coming off. As described above, in the present embodiment, the press-contact ribs 14 are protruded from the substrate 10 at the fixed positions of the sockets, and the wire grooves 14a are formed from above the press-contact ribs 14 downward. By pushing the electric wire W into the electric wire groove 14a, the electric wire W is floated and held so that the insulation displacement terminal can be pressed. In the socket 30, a press contact portion 52 having a notch 52 a for press contact protrudes from the lower surface of the socket 30 so as to protrude therefrom and holds the press contact portion 52 with the press contact rib 14.
If you push it toward, you can press it.

FIG. 5 shows another embodiment of the socket. In the embodiment described above, the socket 30 is disposed perpendicular to the board 10. However, when it is desired to dispose it obliquely, the press contact portion 62 of the terminal 60 is formed obliquely, and the press contact portion 62 projects obliquely from the end of the socket 70. With such a configuration, if the press contact portion 62 is pushed vertically to the press rib 14,
The main body of the socket 70 can be disposed obliquely with respect to the substrate 10. In the above-described embodiment, the pressing ribs 14 are used.
Are formed at the positions where the lamps are to be arranged. However, a plurality of press-contact ribs 14 are formed on the substrate 10 and a plurality of press-contact ribs 14 at positions where the lamps are to be disposed are used. They can be used in common so as to be compatible with patterns. Further, although the electric wire holder is constituted by the rib, it may be constituted by a pin-shaped branch branched so as to lock the electric wire at the end.

Further, if the electric wire W is also wired by pressure welding, the connector 20 can be wired together with pressure welding to each terminal.
